# Symbiosis Developer Tools

## Introduction

Symbiosis Developer Tools include the **Symbiosis JS SDK** and **Symbiosis API**, designed to simplify integration with the Symbiosis protocol and provide developers with robust, scalable solutions for cross-chain and on-chain operations.

* **Symbiosis Core Smart Contracts:** Open source and available on [Github](https://github.com/symbiosis-finance/core-contracts).
* **Security Audits:** Reports available here: [Security Audits](/main-concepts/security-audits.md).

## Features Available via the API and SDK

Both the Symbiosis API and JS SDK provide access to the following cross-chain and on-chain operations:

1. **Swaps:**
   1. **Cross-chain swaps** – Swap *any token* across supported blockchain networks.\
      \&#xNAN;*In short:* [Symbiosis: Cross-Chain Swaps](/main-concepts/symbiosis-cross-chain-swaps.md)
   2. **On-chain swaps** – Swap *any token pair* on a supported network.
2. **Interchain communication** – Transfer tokens to third-party protocols.\
   \&#xNAN;*In short:* [Symbiosis as Interchain Communication Protocol](/main-concepts/symbiosis-as-interchain-communication-protocol.md)
3. **Cross-chain zapping** – Zap any token into a Symbiosis-managed liquidity pool.\
   \&#xNAN;*In short:* [Cross-Chain Zaps](/main-concepts/cross-chain-zaps.md)
4. **Bridging** – Mint or burn tokens to transfer assets across chains.\
   \&#xNAN;*In short:* [Symbiosis Mint-Burn Process](/crosschain-liquidity-engine/synthesizing-process.md)
5. **Cross-chain operation status tracking** – Retrieve real-time transaction status updates.
6. **Emergency handling:**

   1. Retrieve a list of stuck cross-chain operations.
   2. Generate calldata for reverting transactions.

\&#xNAN;*Any token* & *any token pair* refer to tokens that can be exchanged on supported DEXs with
